SPECIFICATION forming part of Letters Patent No. 294,764, dated March 11, 1884.

Application filed August 1', 1883. (No model.)

To all whom it may concern.

Be it known that I, Mari-inw Cocoon-in, a citizen of the United States, residing at Sterling, in the county of Vhiteside and State of Illinois, have invented certain new and useture' of butter-tubs, which latter are now in great demand as a means for packing, preserving, and transporting butter. Such improvements consist, mainly, in novel mechanism for supporting' the truss hoops horizontally at proper distances above each other to receive the staves, and the employment ot' a dropweight to force the staves into such trusshoops while the latter are supported in certain relative positions,

In the drawings, Figure lis a side elevation of my invention with the staves for the first time placed in position. Fig. 2 is a like side elevation, showing` the staves preliminarily driven into the truss-hoops. Fig. 3 is alike elevation exhibiting the final process of tightening the truss-hoops.

A A A are three standards equidistant, either suitably framed together, so as to remain erect, or individually bolted to the floor. Ihe interval between the inner faces of the standards A is equal to the diameter of the hoops and resting temporarily (Fig. l) upon the vertically-movable bottom D.

E is a foot-lever fulcrumed on the crosspiece F, suitably affixed to the standards A.

G isadrop-weight suspended in any suitable way by means ofthe rope II passed over a pulley (not shown) affixed to the beam or ceiling overhead. An additional recess, 2, is formed on the inner face of each standard A, ashort distance below the lower recess 1 for the reception of the circular plate I, asshown -in Fig. 3. i

The operation of my invention is as follows: The operator places his foot on the outer end of the lever E, bringing such en d down upon the ioor, and by the same motion forcing the movable bottom D up against the under edge of the lower truss-hoop, B, as shown in Fig. l, the truss-hoops having been placed in their several positions in the recesses l. rIhestaves are then placed within the truss-hoops around The upper edge of'thc lower truss-hoop, B, is provided on its upper edge with an inward bevel to assist in guiding the lower ends of the staves into proper position. The operators foot is then withdrawn from the lever E and the bottom D thereby drops slightly awayfrom the lower truss-hoop. The drop-weight G is then permitted to fall upon the upper ends of the staves, forcing the latter tightly into suoli truss-hoops. rlhe tub thus held together by the truss-hoop B is then taken from the standards A and fired The process of firing, as is well known,

renders the stav'es more iiexible, and therefore more susceptible of being adapted to each other. rIhe bottom D is then removed and the bottom I placed in the lower recesses 2, and the tub, with its truss-hoops attached, placed within such standards, as shown in Fig. 3, and the staves driven tightly within the truss-hoops by means of the drop-weight G, as aforesaid. The tub is then ready for removal and nal finishing.

The advantages of my invention are, rst, the ease andeonvenience with which the tub may be set up, and, second, the uniformity and force with which the staves are driven into the truss-hoops, and, third, the tub is straightthe entire inner circumference of the latter. l

roo

ened77 at one operation. On the lower lace of the plate I are formed short studs, which fit into corresponding holes in the recesses 2 of the standards A, and thus assist in holding the latter in position.

If preferred, two sets of standards can be used, and thus the inconvenience of changing the plates D and I be avoided.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. The combination of the standards A, provided on their inner faces with recesses 1, the truss-hoops I3, fitted to rest in said recesses, the bottom l) within said standards, the lever E, and fulcruni F, substantiallyT as shown, and for the purpose described.

2. The combination of the standards A, provided with recesses l and 2 on the inner faces thereof, the truss-hoops B, fitted to restin such recesses l, the removable bottoni I, fitted to rest in such recesses 2, the weight G, arranged to be suspended over and dropped upon thc upper ends oll the staves (l within such hoops, and the rope II, substantially as shown, and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
